JNS NA4900UU Needle Roller Bearing

JNS NA4900UU Machined Ring Type Sealed Needle Roller Bearing With Inner Ring, 10mm bore x 22mm outside diameter x 13mm width. Equivalent to IKO NA4900UU, INA NA4900.2RS, NTN NA4900LL, Torrington - Koyo NA4900.2RS.

Machined type needle roller bearings are high precision bearings which consist of machined outer ring with a complement of needle rollers retained and guided by a cage. The bearings feature a smaller cross-section, higher load-carrying capacity, greater rigidity. Therefore, they are useful in making machinery smaller and lighter.
